STOPPER-EXTRAC'IOR. 7

Specification of Letters Patent.

Patented Jan. 23, 1917.

Application filed January 16, 1915. Serial No. 2,554.

I To all whom it may concern:

Be it known that I, VVILsoN M. BRADY, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Stopper-Extractors, of which the following is a specification.

This invention relates to improvements in stopper extractors and has particular reference to a device for extracting cork or similar stoppers from bottles.

vOne object of the invention is to provide an improved construction of stopper extractor that will not mutilate the stopper during the extracting operation but will leave the stopper in practically as good condition, in so far as its function as a stopper is concerned, as prior to its removal from the bottle.

Another object is to provide a stopper extractor of improved construction that may be quickly engaged with the stopper before extracting the same and which will permit of the ready removal of the extracted stopper therefrom.

A further object is to provide an improved construction of stopper extractor that will engage the stopper in such manner as to enable the latter to be rotated in the bottle neck and by such rotation disengaged from the bottle neck.

A still further object is to provide an im proved construction of stopper extractor that may be engaged with the stopper by direct longitudinal pressure thereon and which will not disengage from the stopper during the extracting operation by a pull in the reverse or outward direction.

lVi th these, and other objects in view, the invention is illustrated in the accompanying drawing, wherein,

Figure 1, shows the improved extractor in side elevation. Fig. 2, is a similar view but shows the device in the operated position, as when engaging a stopper. Fig. 3, illustrates the stopper extractor in sectional elevation. Fig. 4, shows a bottom plan View of the detached pin-carrying member of the extractor. Fig. 5, illustrates the detached pin guide head in bottom plan. Fig. 6, shows a longitudinal sectional detail through a portion of the extractor stem and the pincarrying and actuating members thereon and also illustrates the spring catch for holding said members in the normal inoperated position, and Fig. 7, shows a bottle neck with a stopper therein, and also illustrates the improved extractor engaged therewith.

Referring to the several views of the drawing, the numeral 8, designates a central stem having a circular head 9, at one end thereof and in the present instance, provided with a finger engaging-bar 10, at the opposite end. This circular head 9, has a plurality of inclined guide passages 11, extending therethrough from the upper tothe lower side,the lower ends of the said inclined passages terminating at points nearer the center of the head than the upper ends of said passages. A pointed centering pin 12, is provided on the bottom side of said head for a purpose that will presently be explained.

The head 9, and bar 10, in so far as operation is concerned, are both rigid on the stem 8, but they may be formed separately and then attached to the stem if preferred.

A sleeve 13, is slidably mounted on the stem 8, between the head and bar so that it may have a movement longitudinally on said stem, and said sleeve carries a circular pin plate 14:, and a circular actuating plate 15. The pin plate 14, has position between the actuating plate and the head 9, and is preferably smaller in diameter than the actuating plate. This pin plate is preferably of an inverted dish-shape and is provided with a plurality of radial slots 16.

Pins 17, extend freely through the slots in said pin-plate and each pin has a head 18, at its upper end which limits the downward movement thereof through said slot.

The lower end 19, of each pin is pointed so that it may readily be pushed into a cork 9, and preferably project slightly from the lower ends of said passages, when the pin plate is in its upper inoperated position on the stem, as clearly shown in Fig. 3, of the drawing. In their raised position the pointends of the pins 17 are separated from each other to the greatest extent, and are then ready to enter a stopper; and in their lowest position these point-ends being in the stopper come together, as seen in Figs. 2 and 7. When the pins have this lowered position within a stopper or cork, 23, they have a grip on the stopper. The circular actuating plate 15, is also preferably of an inverted dish-shape with its dished under side slightly elevated but over the heads 18, of

the extractor-pins, as is clearly shown in Fig. 3.

From the foregoing-explanation it will be seen that the sleeve 13, pin plate 1 1, and actuating plate 15, are rigid with respect to each other and all may be simultaneously moved in a direction longitudinally on the stem. As the pins 17 are carried by the pin plate they also will move in a longitudinal direction when said pin plate is moved, their direction of movement however, being inclined with respect to the stem 8, about Which they are located.

In order to hold the sleeve, pin plate, actuating plate and pins in a normally elevated position on the stem I provide the latter with a longitudinal circumferential recess 20, in which a spring plate 21, is located. This spring plate has an outwardly curved portion 22, which engages the lower end of the sleeve when the latter is elevated on the stem, and by such engagement serves to hold the sleeve, and the parts carried by the latter, in such elevated position unless suiiicient downward pressure is applied to such parts to depress said spring plate.

In Fig. 7 of the drawing, the extractor is shown engaged with a stopper 23, in a bottle neck 2%. In making this engagement the head 9, is seated on the outer end of stopper with centering pin 12, substantially at the center of the stopper. Slight pressure of the head against the stopper will force the centering pin in the latter. By then holding the bottle in one hand and grasping the circumferential edge of the actuating plate 15, by the fingers oi the other hand and pushing the actuating plate and bottle toward each other, or pushing one toward the other, the pins 17, willbe forced longitudinally into the stopper in an inclined direction, as shown by broken lines in Fig. 7, and the extractor and stop per thereby engaged. By then imparting a gradual rotating movement of the bottle with respect to the extractor, or of the extractor With respect to the bottle, the stopper will be moved in a circular direction in the bottle neck and such rotation will readily free the stopper as the tendency of the latter is to move outwardly during such rotation. If necessary, a slight outward pull on the bar 10, may be made during rotation without in the least releasing the pins from the stopper, and the latter will readily move out from the bottle neck. The operation is simple and effected with but little exertion. After the stopper has been removed from the neck, its end may be grasped by the fingers of one hand while the fingers of the other hand will draw the actuating plate 15 outwardly on the stem,the palm of the hand holding the stem against movement while plate 15, is being moved. This operation will readily withdraw the pins from the stopper.

' Having thus described my invention, what I claims is,

A bottle-stopper extractor having in combination, a stem provided at its lower end with a head having inclined passages 11, through the head; a sleeve 13, slidable on the stem and carrying a pin-holding plate 1 1, having radial slots 16; a pin-actuating plate 15, also carried by the sleeve and positioned above the said pin-holding plate; and pins having heads at their upper end and sharpened points at the other end, said pins extending loosely through the radial slots in the pin-holding plate and having their heads interposed between said pin-plate and the actuating plate, and the pointed ends of the pins extending through said inclined passages in the lower head.

In testimony whereof I aflix my signature in presence of two witnesses.
